Sheet pile design
Mr J. Botterill of Chessington, Surrey, points out some inconsistencies as between various commonly used treatments. In the design of sheet piling many engineers seem to rely on the BSC Piling handbook as the bible. But in the example laid out for the frequently used cantilever wall, the net pressure method is used, and there is no factor of safety at all against overturning!
